11.1" Polished Petrified Wood (Araucaria) Round - Arizona
This is a colorful, 11.1" wide, polished round of petrified wood (Araucaria) from Arizona. It features a mixture of red, orange, yellow and white-blue coloration, as well as excellent wood grain preservation in spots. Comes with an acrylic stand.
Petrified palmwood includes a group of fossil woods that contain rod-like structures within the regular grain of the silicified or agatized wood. Depending upon the angle at which they are cut, these structures show up as spots, tapering rods, or continuous lines. The rod-like structures are sclerenchyma bundles that comprise part of the woody tissues that gave the wood its vertical strength.
